V 3 A e To aZZ whom it may concern," i v Be it known that 1, JAMES W Bd nnm, citizen of the United States, residing at Chi: cage, in the county of Cook and Illinois, have invented-certain new and iisefu'l Improvements in Crushers, of which the following is a specification.

My invention relates to that type of crushers in which two plates aremounted in oppo-l sition and. at a downward inclination, one being stationary and the other reciproca hle,

the ore or other material beingfedhetween the plates and crushezlby a: combined coin- Theinvention may besa id to be in, many respects an improvement upon that fornrof construction set forth in my former Patent hie/758,735, dated May 3, 1904, and; has for its object the. simplification of the machine with an increase in strength and efiiciency,

reduction in the number ofoparts and the elimination of many wear points and also a modified movement of the reciprocating which is attainedva wider range ofiise, in the accompanying"drawings and'in the plate whereby reatercrushingpower isobtained and a nerrange of adjustment by greater uniformity inthe product.

following description p set forth a prefeired practical embodiment s theeonstructiqnalfea tnres are, however, capable of W l(lQlfilOdll'lcation without departing from drawing and description are to be construed sarily limiting the invention. Y t 7 y In the drawings: Figure-l 1s a transverse vertical section on the line 1-'i of Fig. 2

tail, the numeral 11 designates the'l'nachine bed plate having a'central vertical opening 12 for the discharge of the crushed product into a suitable receptacle, .Snpported upon thedbed plate and strengthened by the r hs'lii is the substantially rectangular machine casing units, I-have: illustrated a: duplex: inaelnne in into two crushing chambers 15, 15 arranged one upon each sure of the vertical axis of the e so indicated thereon is,

I the essence lot] the invention it will he understood that the v ii an illustrative'sense and not as unneces which two crushingnnitsfare: mounted side by side to operate in intermita machine, .'I he two 'nnitsb'eing in allroi spects dentical the description of one will snliice for botln At onesideof the machine and forming one wall of the crushing sham ber- 115,15 disposed an inclined plate 18 formed of a rear supporting portionli'c and? f a front Wear portion 18, the upper edge of thisplate is provided with an hour glassslot 19 for, the reception of theihclt20 h mns; of which the plate is secured, to the machine casing'fito provide for slight pivotal move-,1, ment,-the main body of the'plate is disposed i at an inclination to the vertical while V lower portionthereof is disposed in a sub}; n l y erti cal position. Havinga d tailed engagement with the lower portion of the plate is an ad usting barQI'eXtendingthe full width of the plate and between said bar i and the inner Wall ofthe casing itself at 2 2 is mounted an adjusting screw 23, by means ofwhichjthe lower end of the plate 16 lead x justed ina horizontal direction'npon the" boltl20fasa pivot'.- Thefrear face of the sup portin%;;p1ateportion 17 is. provided with a strengt tions in the form of teeth extending horis downwardly that these in size from pointing. It will be observed 18 is smooth.

' Centrally of the machine in the bearing 'ln'ackets fli is jonrnaleda. rock shaft-28,;. eachQendof which is preferably squared r i I as indicated in dotted lines at 29 to receive a walking beam 30, the free extrelnitie's of which beams are oined by means of the (rrossn odi, 30 and the connecting rod to, the crank 32 of shaft 'driveniby a" pulley 34 from any suitable source ofpower.

j Upontherock shaft 28i'skeyed a pair of sleeves 35 each ofwhich has upwardly pro-;

jecting therefrom a pair ofarlns tel-mi natingin knuckles 36. The alined knuckles extending into knuckles 38.for ned on the npper end'swf a swingingplate 39.; This swinging plate is, likethevplate16, of du 'inenti vvherehy: the ,tvyo portions mayF-h I v v ening rib 24, whilethe frontface of theywearfplate 18 ISPI'OVldGCl With corrugazontally thefull width of the plate and rrngations diminish gradually the top toward, the bottom" and; that the lower 781131031: face 2-6 of the'plute 300i the two-sleei es 35 are connected by at ing L1 open above. Although the machine r rod 37 Win h r S rves as. a pm-tle,,1ts ends may include one or any number of'crnslrx' an anti-friction roller, 45. i

It will be observed that upon the actuation of the walking beams 30 the shaft 3;) rocked so as to move the lmucldes 36 about the axis of the shaft as a center through an arc confined substantially between a wrtical plane passing through such axis and a, plane disposed at an angle of approximately 45 to such vertical plane. lly such rocking movement of the knuckles 36 the plates,39 are alternately reciprocated in a general vertical direction. However. it will be seen that the upper end of the plate moves in a curved line whereas the lower end of the plate moves in a verti cal path along a substantially right line upon its rolling support 45. The result is a con'ibined compressive and rnhbing'action between the opposed faces of the plates 16 and 3!), the compressive action being great est in the upper portion of the machine where the material is first introduced, while at the lower outlet portion between the smooth surfaces 26 and 13 the action becomes a. purely rubbing one. By the ad justnient of the lower ends of the plates toward and from each other the fineness of the product may be accurately controlled from coarse granular particles to an im palpable powder. As the ro lers 45 are mounted for complete freedom of movement between the abutment bar 4-4 and the rear face of.thc reciprmaiting plates there is a pure rolling engagement tbercbetween and the friction at this point, which would otherwise be enormous, is practically eliminated. i
